How to Restore Deleted Calendar on iPhone

People who like to stay on a schedule use the built-in Calendar app to keep track of their meetings and other events. They may sometimes even have multiple calendars to separate their personal and professional lives. As is the case with any form of data, your calendars are prone to accidental deletion. What’d you do if you notice that some of your calendar events are missing when you open the app one day?

Well, calendars could get deleted due to various reasons. Sure, the most common reason is the accidental removal of calendars and calendar events. Apart from this, potential issues during a software update can wipe the data off your iPhone. Or, you could lose your calendars if you forget to transfer the data after purchasing a new iPhone. On the bright side, all the calendars and calendar events you’re unable to find on your iPhone can still be recovered.

Whether you lost your calendars due to a corrupted update or you accidentally deleted some events and want to roll back the changes, you can utilize any of the following methods to restore deleted calendars on iPhone.

Method 1: Restore Deleted Calendar from iCloud

In the first method, we’ll take a look at how you can use iCloud to get back deleted calendars on your iPhone. You can retrieve lost and missing calendars in two different ways using iCloud, and it all comes down to your preference and whether or not you have access to a computer.

1.2. Restore Deleted Calendar from iCloud Backup

If you don’t have access to a computer, things get slightly more complicated. This method requires you to erase your iPhone and restore it from a previous iCloud backup. Before you proceed, make sure you have fully backed up your iPhone to iCloud prior to the date the calendars were lost or removed.

Step 1. Launch the Settings app on your iPhone. Scroll down and tap on ‘General’ from the settings menu.

Method 3: Restore Deleted Calendar from iTunes Backup

Most iPhone users who don’t pay for iCloud rely on iTunes to back up their data. This technique is for those users who use iTunes and don’t want to install any additional software to restore deleted calendars. It’s similar to the iCloud backup restoration method, except that you’ll use a local backup stored on your computer. Once again, only proceed with this if you’re certain that you backed up your iPhone prior to the date the calendars were deleted or lost.

Step 1. Make sure you have the latest version of iTunes installed. Connect your iPhone to the computer using the included USB to Lightning cable and launch iTunes. Now, click on the iPhone icon located below the menu bar as shown below.

Click on the iPhone icon on iTunes

Step 2. This will take you to the device summary section within iTunes. Here, under the Backups section on the right pane, click on ‘Restore Backup.’

iTunes will prompt you to turn off Find My on your iPhone before you’re allowed to restore the data stored in it. To disable it for the time being, head over to Settings -> Apple ID -> Find My on your iPhone.

Keep your iPhone connected to the computer and wait for iTunes to complete the restoration process. Once done, you’ll be able to find all the lost calendars and events within the Calendar app like they were never deleted in the first place. Do keep in mind that all the data that were added to your iPhone after this particular backup will be lost during the process, so move any important files that you may have somewhere safe.

Bottom line

From now on, you don’t need to panic when you lose or accidentally delete your calendars and calendar events. As you can see, there are multiple different ways to restore missing calendar events on your iPhone. It’s just easier with a computer since you can recover lost calendars without having to erase your iPhone using or a third-party software such as UltData.
